Powerflex Trailing Arm to Knuckle Bushings 2002-2007 WRX/STI

Powerflex bushings are made from polyurethane so they flex far less than the squishy stock rubber bushings. Stiff bushings mean more precise alignment, better suspension control, and better steering feel.

Note that it is the nature of polyurethane to squeak eventually. Lubricating them periodically will reduce this tendency, but we will not take back any polyurethane suspension product because of noise.
